I've had a look at the PR, and it seems there is some problem
about shared / non-shared values of __cpu_model.

I think your best bet would be to re-open the PR and add the
appropriate info there - how you configured your compiler,
output of gfortran -v, etc.

One think that you could try as a workaround would be to
specify -static-libgcc.
